1 This invention relates to building siding material having arigid,'fibrous panel base and an impressed or embossed face whichsimulates masonry such as brick work and interveningmortar joints. Moreparticularly, this invention is concerned with the problem of concealingthe joints between assembled panel units of the foregoing type havingthe masonry-simulating areas thereof surfaced with mineral particles orgranules of one color, and the mortar joint-simulating areas thereofsurfaced with mineral particles or granules of a different or blendingcolor.

Heretofore, it has been diflicult with siding panels'of the abovecharacter effectively to conceal the actual joints between the assembledpanels so as to achieve an appearance which closely simulates masonry orthe like. These panels are commonly formed of rigid, fibre compositionboard which is surface impregnated with bituminous material, such asasphalt, coated with a waterproof asphaltic coating on the face thereofto be exposed, this coating being surfaced with mineral granules orparticles of brick color applied to the brick-simulating areas and ofcontrasting color applied to the mortar joint-simulating areas. Whensuch panels are applied to a building in interfitted, coplanar relation,it is impossible, as a practical matter, to obtain such uniform abutmentof the edges of adjacent panels as will entirely conceal the joint linesor crevices between the panels. This failure is due particularly toirregularities in the cutting of the panels which prevents the desirederected relation therebetween, or to carelessness in their erection.

Actually, it is extremely difiicult, if not impossible, in themanufacture of the composition board to obtain the exact sizes desired.The minimum tolerances to which board manufacturers can ordinarily workare about 3 at each edge. Consequently, the horizontal edges of adjacentfinlshed panels do not fit tightly together when ap plied in assembledrelation to one another and the horizontal crevices occurring at thejoints between these panels, even when skillfully applied, being of darkcolor, as compared to the color of the mineral granules applied to thebrick-simulating areas as well as to those applied to the mortarjoint-simulating areas, serve to set up the panel outline and destroythe desired illusion of an integral wall of natural masonry. 7

It is the primary object ofthe present invention to overcome theforegoing disadvantages by providing building siding panels havinggranules of brick color applied to the brick-simulating areas andcontrastingly colored granules applied to the 2' mortar joint-simulatingareas with simple and novel means along one longitudinal margin of eachpanel for effectively concealing the horizontal joints between adjacentassembled panels,

without requiring special skill or care in their assemblage.

In accordance with the present invention, the foregoing and relatedobjects may be attained by providing a rabbet, cutout or recess alongone longitudinal margin of a rectangularly formed, ship-lapped panelblank. This recess is filled with asphaltic coating, when the latter isapplied to the face of the panel that is to be exposed. The coating,particularly the portion which fills the recess, is surfaced withgranular material so that there may be provided, along the longitudinalmargin defined by the coating-filled recess, a rolled, compactedmasonry-colored granular surface which extends substantially the entiredepth of the recess slightly beyond the edge of the panel which is toabut an edge of an overlapped panel. In this manner, I effect a tightjoint between the abutting panels, thereby effectively concealing anyjoint crevices that may be formed, unavoidably or otherwise, betweensaid abutting panels.

Other advantages and features of the invention will become readilyapparent in the following description and the accompanying drawing inwhich,

Fig. 1 is a plan view of a masonry simulating siding panel;

Fig. 2 is a similar view of three such sidin panels showing the mannerin which they are laid in coplanar, abutting relation to form anexterior covering for a side wall;

Fig. 5 is a fragmentary sectional view diagrammatically illustrating themanner in which the rabbeted marginal edge ofa panel may be providedwith an overhanging rolled, compacted masonry colored granular surface.

Referring to Fig. 1 of the drawings, the numeral l0 designates a panelof building siding material. This panel preferably comprises asubstantially rigid base of fibre insulation board II, generallyrectangular in shape, and provided with ship-lap flanges I! at onelongitudinal and one transverse edge thereof, while the other two edgesof the panel are formed in complementary relation to the first-namededges by undercutting thereof to provide projecting ship-lap flanges l3.Thus, the upper face of the flange l3 formsa continuation of the face ofthe panel. These panels are adapted to be applied in abutting, coplanarrelation, with the ship-lap flange l3 of one panel overlapping thecomplementary flange l2 of the adjoining panel, as illustrated in Figs.2 and 4, to form a water-tight joint therebetween.

In accordance with the present invention, the panel blank H, in additionto being properly cut to size and provided with complementary shiplapflanges l2 and I3, as previously described, is provided with a rabbet,notch or recess 25 extend-. ing for the entire length along onelongitudinal edge of the blank. As bestshown in Fig. 3, this recess orrabbet 25 has its sides or faces 26 and '21 extending preferably,although not essentially,

at right angles to each other.

The panel blank thus provided may then be impregnated with asphalt orother similar bituniinous material in order to stiffen the board andbind the surface fibres together against delamination. The approximateextent of this surface impregnation is indicated by the stippled borderareas, as at I4. The exposed face of the thus impregnated panel base isthen coated with a layer of thermoplastic asphaltic coating material 15,such as high melt point asphalt, combined with suitable filler material.In addition to forming a layer of substantial thickness on the flatsurface of the blank, the coating will also flow over the edge thereofand fill the recess or rabbet 25 substantially to the level of the layeron the flat surface so as to be continuous there with. As the asphaltlayer l5 cools, it becomes bonded to the surface and will be retained inthe rabbet 25 so as to completely fill the latter, thus providing anadditional thickness of coating along this edge of the panel base.

While the coating layer, including the vertically extending portionthereof along the filled recess, is still in a plastic, adhesivecondition, it is surfaced with granular material ifi of mineralcharacter-and of suitable color to simulate conventional brick, stone orthe like. These granules i6 may be partially imbedded in the coating, asby the application of suitable roll pressure. Subsequently, granularmaterial it of similar character, but of a different or distinguishingcolor to simulate mortar, may be applied over the entire flat uppersurface. The blank may then be subjected to a selective embossingoperation which partially imbeds the second layer of granules only inthose areaswhich are to simulate mortar joints, while at the same timeforming uniformly spaced narrow grooves 29 to give the desired reliefeffect. After the second colored layer i8 has been pressed in thedesired pattern, the excess granules not imbedded in the coating,particularly those cov-, ering the masonry-simulations, may be removedin any suitable manner to expose the masonrysimulating areas H separatedand set on in relief by the diiferently colored mortar joint-simulatinggrooves 20.

In the case of brickwork, the masonry simulating areas I! take the formof oblong-shaped formations of suitable width and length to simulatebrick arranged in horizontal rows or courses, generally five in number,and in staggered order. As shown in Fig. 1, the upper longitudinal edgeof the panel is defined by a continuous horizontal mortarjoint-simulation 20 and each of the succeeding rows or courses arespaced apart by a similarly extending mortar joint-simulation of uniformwidth. The adjacent brick-like formations [1 in each row or course arespaced apart or set off from each other by a. vertical mortarjoint-simulation 2|. Atv the lower longitudinal edge of the panel, thespaced brick-like formations extend to the very edge thereof, thusdefining and constituting a part of the projecting ship-lap flange l3.At the ends of the alternate rows or courses there are formed part-brickformations lla which are of the same character, material and width asthe whole-brick formations H but different therefrom in length. Thelengths of the two end part-brick formations Na in each of thesealternate rows, when combined, are equal to the length of the individualintermediate whole-brick formations. A series of uniformly spaced narrowgrooves 22, simulating wirescorings, are formed transversely on all ofthe part Ibrick formations and on some of the intermediate 7 whole-brickformations, as shown.

When the panels are joined endwise in abutting coplanar relation, asshown in Fig. 2, the partbricks of one panel abut against'thepart-bricks of the other, thus overlapping the vertical joint betweenthe units and serving effectively to conceal said joint.

In the further practice of the present invention, the filled and granulesurfaced rabbeted margin of the panel is subjected to a. rolling andcompacting operation preceding the aforedescribed embossing operationand, preferably, immediately following the step of applying the layer ofmineral granules l6 and partially imbedding this layer in the coating.

In this operation, illustrated in Fig. 5, the panel It! may be conveyedby supporting rollers 35, or

other suitable means, into contacting position with a roller wheel 36 insuch 'manner' that the vertical edge is of the projecting ship-lapflange l3 will abut against the roller. The roller wheel may be formedof wood or other suitable material and, as shown, is provided with areduced upper portion 38, having a radius approximately to 1%" less thanthat of the lower portion and having its horizontal face 39substantially aligned with the horizontal face 26 of the rabbet 25. Therqller wheel will freely rotate about its vertical axis 31 as the edgeH! of the advancing ship-lap flange [3 of the panel is brought intocontact therewith. This edge l9 serves as a firm guide to permit theperiphery 40 of the reduced portion 38 to compact and shape uniformlythe vertically extending granule surface 6 5.

The roller wheel permits the rolled, compacted and adhesively anchoredgranule surfaced layer to extend somewhat beyond the vertical edge IQ ofthe ship-lap flange l3, thus providing an overhang of say 3% to 1%"depending upon the radius of the reduced portion of the wheel.

There is thus provided a simple but effective means for concealing thepanel joint or crevice between two adjacent assembled panels and thuscarry out the illusion of a wall of natural masonry. It will be observedwith this construction that when a plurality of panels it) are properlyarranged in edge abutment and in coplanar relation, the loweroverhanging longitudinal edge 45, of the projecting ship-lap flange 93,formed as above described, will be abutted against the edge 43 of theship-lap flange l2 forming the horizontal edge of the uppermost mortarjointsimulating groove 20. The coating and the granavoidably may beformed ules at the edges 45, 46 may readily be caused by slight pressureto become intermingled or interlaced with one another, thus effectivelyconcealing any opening or crevice that may otherwise be exposed. Such anopening or crevice that unbecause of irregular cutting of the panelblanks or may be formed due to careless erection, as previouslyindicated, is shown at 48, although this showing is somewhat exaggeratedfor illustrative purposes.

In addition to concealing the panel character of the constituent sidingmaterial, the provision of the rabbet along the margin of the panel inaccordance with the present invention possesses further advantages whichmay be referred to briefly. For example, the additional volume of panelcoating filling the rabbet offers a measure of added protection againstany possible injury or damage that may occur to this projecting marginaledge ofeach of the panels during storage, transportation andapplication. Then, too, the additional bonding surface thus affordedbetween the coating and the impregnated surface of the panel blank tendsto lengthen the life of the panel along that critical area which issubjected to erosive action by the drainage of rain water from thesurfaces of the assembled panels.

The present invention thus renders it'possible to provide siding panelssurfaced with difierent colors of mineral particles or granules arrangedrespectively to simulate masonry faces and separating mortar joint lineswhich, when applied to a building in assembled coplanar relation,produce an effect pleasing to the eye and, at the same time, present theappearance of a well simulated masonry wall.
